This Christmas, someone could unwrap a $1 billion surprise as the Mega Millions jackpot reaches a staggering amount ahead of Tuesday night’s drawing. According to the lottery’s website, the lucky winner who opts for a lump-sum payout would walk away with $448.8 million—more than enough to stuff plenty of stockings.

If the jackpot is claimed, it would mark the largest Mega Millions prize ever awarded in December, making the Christmas Eve drawing at 11 p.m. ET even more festive.

The Mega Millions jackpot has seen several historic payouts in recent years. The record-holding prize, $1.6 billion, was won in 2023 by a single ticket holder in Florida.

As hopeful players prepare their tickets, this Christmas Eve could deliver more than just holiday cheer for one lucky winner.
